[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] like Figure 1-3 As shown, a composite material winding device proposed in this embodiment includes a box body, a wire-releasing mechanism is provided on the top of the box body (wherein, the specific structure of the wire-releasing mechanism 2 can refer to the existing structure, and will not be repeated herein.), and the box body is provided with:

[0027] A winding mechanism for winding a composite material wire;

[0028] The winding mechanism is located below the pay-off mechanism 2;

[0029] The reciprocating block 3 is located above the winding mechanism and can reciprocate along the axial direction of the core shaft 6. A center hole 4 is opened in the middle of the reciprocating block 3. The composite material wire 5 released from the wire release mechanism 2 passes through the center hole 4 of the reciprocating block 3 and enters the winding mechanism;

[0030] Specifically, the reciprocating block 3 is set to be an annular structure.

[0031] The vacuum pumping mechanism is used to vacuum the interior of the box body 1.

[0032] In this way, the reciprocating motion of the reciprocating block 3 drives the composite material wire 5 released from the wire-releasing mechanism 2 to be wound on the core shaft 6, and the winding is more uniform, not limited by the workshop space, and the space utilization rate is high; the inside of the box 1 is evacuated by the vacuum device, so that the composite material wire 5 is in a vacuum environment during the winding process, is not disturbed by the air, and is wound more uniformly and tightly, thereby improving the winding quality of the composite material.

[0033] Furthermore, if Figure 1 As shown, the winding mechanism includes:

[0034] The mandrel 6 is used to wind the composite material wire 5, and the two ends are rotatably connected to the two side walls of the box body 1 through rotating rods;

[0035] The output end of the driving motor I7 is connected to the rotating rod on one side, driving the rotating rod to rotate, thereby driving the core shaft 6 to rotate, and winding the composite material wire 5 released by the wire-releasing mechanism 2.

[0036] Furthermore, a driving mechanism for driving the reciprocating block 3 to reciprocate is provided, a cross bar 8 is fixed between the inner side walls of the box body 1, the height of the cross bar 8 in the box body 1 corresponds to the reciprocating block 3, the reciprocating block 3 and the cross bar 8 are slidably connected through a sliding structure, the driving mechanism includes a driving motor II 12 located outside the box body 1 and a screw 9 arranged below the winding mechanism, the two ends of the screw 9 are respectively rotatably connected to the two side walls of the box body 1, a screw barrel 10 is threadedly connected to the screw 9, the middle part of the screw barrel 10 is fixed to the reciprocating block 3 through a traction line 11, the output end of the driving motor II 12 is connected to the screw 9, can drive the screw 9 to rotate, and then drive the screw barrel 10 to reciprocate along the axial direction of the screw 9, and drive the reciprocating block 3 to reciprocate along the cross bar 8 through the traction line 11, because the composite material 5 line released by the unwinding mechanism 2 passes through the central hole 4 of the reciprocating block 3, the reciprocating motion of the reciprocating block 3 can drive the composite material line 5 to move in both directions along the axial direction of the core shaft 6, thereby ensuring uniform winding on the core shaft 6.

[0037] Among them, Figure 2 and Figure 3 As shown, the sliding structure includes a slide groove 13 provided on the cross bar 8 and a slider 14 provided on the reciprocating block 3, the slide groove 13 extends along the length direction of the cross bar 8, and the slider 14 slides into the slide groove 13. The specific structure of the slide groove and the slider can refer to the existing structure, and will not be repeated in this article.

[0038] In this embodiment, Figure 1 As shown, the vacuum device includes a vacuum pump 15 and a vacuum tube 16, one end of the vacuum tube 16 extends into the box 1, and the other end is connected to the vacuum pump 15. When the vacuum pump 15 is started, the air in the box 1 can be extracted through the vacuum tube 16, and a vacuum environment is formed in the box 1 to prevent the air from affecting the winding of the composite material, so that the composite material wire 5 can be wound on the core shaft 6 more evenly and tightly.

[0039] It should be noted that, in other embodiments, the specific structure of the vacuum device may also be other structures, such as a vacuum generator, etc., depending on the specific circumstances.
